Filtering levels to create floor plans by room

Developers

Hi All,

Trying to collect all levels from a project and using to create sectioned rooms by floor plan. I have managed to make it work in Dynamo (python) however, I am trying to convert it to a button.


import clr
clr.AddReference('RevitAPI')
from Autodesk.Revit.DB import *

clr.AddReference("RevitNodes")
import Revit
clr.ImportExtensions(Revit.Elements)

doc = __revit__.ActiveUIDocument.Document
uidoc = __revit__.ActiveUIDocument

t = Transaction(doc, "Floor Plan by Room")

level = FilteredElementCollector(doc).OfCategory(BuiltInCategory.OST_Levels)\
											.WhereElementIsNotElementType()\
											.ToElements()

for l in level:
	if l.Name == "Level 1":
		level = doc.ActiveView.Document.GetElement(l.Id)
		break

filter = Architecture.RoomFilter()
collector = FilteredElementCollector(doc, level.Id).WherePasses(filter).ToElements()
	
t.Start()

for room in collector:
	
	viewtypeid = level.GetTypeId()
	levelid = room.LevelId
		
	roomview = ViewPlan.Create(doc, viewtypeid, levelid)
		
	roombb = room.get_BoundingBox(level)
	rmax = roombb.Max
	rmin = roombb.Min
	newmax = XYZ(rmax.X + 1, rmax.Y + 1, rmax.Z)
	newmin = XYZ(rmin.X - 1, rmin.Y - 1, rmin.Z)
	newBB = BoundingBoxXYZ()
	newBB.Max = newmax
	newBB.Min = newmin		
		
	roomview.CropBoxActive = True
	roomview.CropBox = newBB
	
	roomview.Name = room.LookupParameter("Name").AsString()
	output.append(roomview.ToDSType(True))

t.Commit()

This is the code written. And the error give in “viewId is not a view”

Any suggestions are appreciated.

Many thanks

Hello,
level.GetTypeId() return an ElementId of a LevelType, according to the API Revit Doc you need a viewFamilyTypeId

Note:
pyRevit has a dedicated forum

Thank you I was not aware of the forum :slight_smile:

your collector should fail when you are feeding level.Id as that particular constructor requires viewId. Instead, you should use LogicalAndFilter with your RoomFilter to filter out rooms of specific levels. Same goes for the ViewPlan.Create constructor input.

I got it to work finally, using the following code, might be useful for someone.

import clr

clr.AddReference(‘RevitAPI’)

from Autodesk.Revit.DB import *

clr.AddReference(“RevitNodes”)

import Revit

clr.ImportExtensions(Revit.Elements)

doc = revit.ActiveUIDocument.Document

uidoc = revit.ActiveUIDocument

t = Transaction(doc, “Floor Plan by Room”)

plan = FilteredElementCollector(doc).OfClass(ViewFamilyType).ToElements()[0]

toggle = True

output =

if toggle:

filter = Architecture.RoomFilter()

collector = FilteredElementCollector(doc).WherePasses(filter).ToElements()



t.Start()



for room in collector:



    viewtypeid = plan.Id

    level = room.LevelId

   

    roomview = ViewPlan.Create(doc, viewtypeid, level)      

    roomview.Name = room.LookupParameter("Name").AsString() + " - Plan " + str(room.Id)

   

    t.Commit()

   

    t.Start()

   

    roombb = room.get_BoundingBox(doc.ActiveView)

    rmax = roombb.Max

    rmin = roombb.Min

    newmax = XYZ(rmax.X + 1, rmax.Y + 1, rmax.Z)

    newmin = XYZ(rmin.X - 1, rmin.Y - 1, rmin.Z)

    newBB = BoundingBoxXYZ()

    newBB.Max = newmax

    newBB.Min = newmin      

   

    roomview.CropBoxActive = True

    roomview.CropBox = newBB

   

    roomview.Name = room.LookupParameter("Name").AsString() + " - Plan " + str(room.Id)

    output.append(roomview)

   

t.Commit()

else:

output.append("Set to True")
